To evaluate the performance of the updated WB part of HGCN+, we generate 100 hours of WB data with signal-to-noise ratios (SNR) ranging in 0~40 dB using the speech and noise provided by INTERSPEECH 2020 DNS Challenge (DNS-2020) [1]}. We divide the data into training and validation set by 4:1. For testing, we generate 540 noisy-clean pairs with 3 SNRs (-5 dB, 0 dB, 5 dB) using the noise and speech that didn't appear in the training or validation set.
